THREAD GUIDE Application filed latch 16, 1929, Serial No. 347,502, and in Germany March 19, 1928.

This invention relates to a thread guide for reeling threads on reels and bobbins. The devices hitherto used for this purpose have the drawback that in the course of time they gradually get cut into through the constant friction with the thread in one and the same place. This incision results in the formation of sharp edges which are dangerous for the guided thread, more particularly when delicate textile materials such as silk or artificial silk are being Worked up. V

The disadvantages described may be avoided by the thread guide being made slotted and being arranged not only to perform the requisite to and fro motion for producing the desired win-ding, but in addition a to and fro travelling motion at right angles thereto. This prevents the thread always coming in contact with the same part of the thread guide during the winding operation and thus causing uneven wear, so that edges may be formed which are detrimental to the thread.

The described motion of the thread guide may be produced by two separate motions or by a motion which can be resolved into two components lying in the desired directions. For instance a bar supportlng the thread guide or guides may be fixed eccentrically to rotary discs. The bar may also be suspended or attached to swinging members and the to and fro motion be produced by a connecting rod. All these cases employ a parallel crank motion.

The thread guide may be constituted by two vertical wires or small bars having a narrow slot between them.

A particularly suitable constructional form is one in which the slot-shaped thread guides are formed by'wirestirrups mounted 40 next to one another on a bar. This constructional form of the invention has the advantage that the thread when laid on the guide is automatically engaged by it.

In the drawing two constructional forms of a thread guide according to the invention are shown diagrammatically.

In Fig. 1 the slot-shaped thread guides are formed by a number of wire stirrups (1 arranged next to one another to form a series of arches. They are fixed on a bar 6. The

horizontal to and fro motion for producing the crosswise winding and the up and down motion of the thread guide a are produced by means of discs 0 which support the bar I) on pins 01. v

In the constructional form shown in Fig.

2 motion is imparted to the bar I) supporting the thread guides a by means of a connecting rod e, the bar b being guided in arcs b links 7'' which are journalled in layers g, so t at the bar has an arcuate parallel displacement imparted to it, which can be resolved into two components.

What We claim is:

1. A thread guide for reeling threads on reels and bobbins and the like, having a slot for guiding the thread and means for imparting to the thread guide a motion along a path inclined to the direction of the slot while maintaining the slot parallel to its initial position.

2. A thread guide for reeling threads on reels, bobbins and the like, comprising a bar, a plurality of wire stirrups mounted thereon so as to form slots between adjacent stirrups and means for imparting to the thread guide a motion in the direction of the slots and a motion at right angles thereto.

3. A thread guide for reeling threads on so reels and bobbins and the like, having a slot for guiding the thread and means for guiding the thread guide in the direction of its slot and at right angles thereto while maintaining the slot parallel to its initial position. v

4. A thread guide for reeling threads on reels and bobbins and the like, having a slot for guiding the thread and rotatable members pivotally connected to the thread guide for guiding the thread guide both in the direction of its slot and at right angles thereto. I

5. A thread guide for reeling threads on reels and bobbins and the like, having a slot for guiding the thread and link members pivotally connected to the thread guide for guiding the thread guide in the direction of its slot and at right angles thereto while maintaining the slot parallel to its initial position.

6. A thread guide for reeling threads on reels and bobbins and the like, comprising a bar, a slotted member fixed on said bar and adapted to guide the thread and means for moving each point of said bar in a circular path while maintaining the bar parallel to its initial position.

7. Thread guides for reeling threads on reels and bobbins and the like, comprising a bar, a slotted member fixed on said bar and adapted to guide the thread and means for reciprocating each point of said bar on a circular path while maintaining the bar parallel to its initial position.

8. A thread guide adapted to be used in reeling thread, comprising a member having a slot adapted to guide the thread, links pivotally connected at one end to said member and at their other end to fixed pivots, said links having their pivot points equally spaced, and means for moving said member.

In testimony whereof, I have signed my name to this specification this 26th day of February, 1929.
